Definitions

  • the invention relates to lubricating performance additives for metal processing or as a lubricant for machines.
  • Native oils and blown native oils have the disadvantage that they are not water-miscible and therefore emulsifiers must be added when used in water-miscible lubricants.
  • native and alkoxylated native oils contribute only to a limited extent to the lubricity of lubricants.
  • the present invention therefore relates to the use of lubricating power additives comprising the reaction product of at least one alkylene oxide and at least one stand oil and / or a blown native oil as lubricants for metalworking or lubricants for machines, wherein the ratio of stand oil and / or blown native oil Alkylene oxide 30-50 wt .-%: 70-50 wt .-% is.
  • Alkylene oxides in the context of the invention are ethylene oxide, propylene oxide, 1,2-butylene oxide, 2,3-butylene oxide, 1,2-pentylene oxide, 2,3-pentylene oxide, 1,2-hexylene oxide, 3-methyl-1,2-pentylene oxide, 2,3-octylene oxide, 4-methyl-2,3-octylene oxide, 4-methyl-1,2-hexylene oxide and / or 3-methyl-1,2-butylene oxide, with ethylene oxide being particularly preferred.
  • the above alkylene oxides are commercially available products, e.g. at BASF AG.
  • Preferably used are their refined variants.
  • Blown native oils in the context of the invention are air-supplied polymerized native oils, which are prepared by blowing in hot air at temperatures of preferably 100 to 150 ° C. Through the treatment, an enlargement of the molecule takes place via oxygen bridges, as described, for example, in US Pat BASF Handbuch Lackiertechnik 2002, p. 36 (ISBN 3878703244 ). Blown native oils typically have a kinematic viscosity (according to DIN 51562) at 40 ° C between 100 and 10,000 mm 2 / s. The aforementioned blown native oils are commercially available products, eg available from Gustav Heess.
  • Stand oils in the context of the invention are air-tight polymerized native oils, which are prepared at temperatures of 260 to 300 ° C. Through the treatment, an increase in molecular size takes place via polymerization reactions of the double bonds, as described, for example, in US Pat BASF Handbuch Lackiertechnik 2002, p. 36 (ISBN 3878703244 ). Stand oils typically have a kinematic viscosity (according to DIN 51562) at 40 ° C. between 100 and 10000 mm 2 / s.
  • the aforementioned floor oils are commercially available products, eg available from Alberdingk Boley GmbH.
  • the lubricating performance additives may also contain other additives which vary according to the application, e.g. commercial defoamers, surfactants, dispersants, solubilizers, biocides, high pressure additives, antiwear additives, corrosion inhibitors, antioxidants, alkalizers, complexing agents, sequestering agents, demulsifiers, viscosity index improvers, flame retardants, lubricity improvers, perfumes and / or dyes.
  • the lubricating performance additives of the invention may also contain emulsifiers, but the miscibility with water is already given without emulsifiers.
  • Reaction product is the product formed in the alkoxylation (reaction with the alkylene oxide) of at least one standing oil and / or a blown native oil in the presence of a catalyst.
  • alkoxylation reaction with the alkylene oxide
  • the conditions listed below under the process according to the invention apply.
  • the ratio is from 30-50% by weight of stand oil and / or blown native oil to 70-50% by weight of alkylene oxide.
  • reaction product of blown rapeseed oil with ethylene oxide is particularly preferred. Very particular preference is then given to a ratio of 30-50% by weight of blown rapeseed oil to 70-50% by weight of ethylene oxide.
  • the preparation of the slurping performance additives used in the present invention is accomplished by reacting at least one alkylene oxide with at least one standing oil and / or blown native oil in the presence of a catalyst.
  • the reaction product is preferably formed at a temperature of 100 to 190 ° C and a pressure of 1 to 6 bar using a nucleophilic catalyst.
  • Nucleophilic catalysts are, for. Alkoxides, preferably alkali metal alkoxides, more preferably sodium methoxide, hydroxides, e.g. Sodium hydroxide or amines, e.g. Triethanolamine.
  • the reaction temperature is preferably in the range of 140 to 180 ° C, particularly preferably 160 to 180 ° C.
  • the catalyst used is preferably alkali metal alkoxides, more preferably sodium methoxide.
  • the standing oil, the blown native oil or a mixture of both oils may be used.
  • the reaction with the alkylene oxide preferably takes place in the ratio of 1 to 99% by weight of stand oil and / or blown natural oil to 99 to 1% by weight of alkylene oxide. Particularly preferred is the ratio of 30-50% by weight of stand oil and / or blown native oil to 70-50% by weight of alkylene oxide.
  • the lubricating performance additives can also be used as lubricants.
  • the term lubricants encompasses all lubricants, in particular those according to ISO 6743.
  • lubricating performance additives as lubricant for metalworking or lubricant for machines in all lubricants is possible according to ISO 6743.
  • the lubricating performance additives are preferably used in water-miscible or water-mixed cooling lubricants. These are described in DIN 51385. between each other, including between the respective areas and preferred areas in any combination.
  • Example 1 Reaction product of 40% blown rapeseed oil and 60% ethylene oxide.
  • the reaction product had a kinematic viscosity (according to DIN 51562) at 40 ° C. of 750 mm 2 / s.
  • the reaction product was dissolved at 25 ° C to 0.2%, 1% and 5% completely in demineralized water (deionized water). This resulted in transparent solutions with weak opalescence.
  • aqueous solutions of a commercially available ethoxylated native oil namely castor oil ethoxylate with 36 moles of ethylene oxide (EO) per mole of castor oil (Emulsogen EL 360, Fa. Clariant), were tested.
  • EO ethylene oxide
  • the blank values of demineralised water are 36.8 mm 2 for the wear cap and 800 N / cm 2 for the pressure absorption.
  • the lubricating performance additive according to the invention in aqueous solution has a significantly higher pressure uptake than the commercial ethoxylated native oil used in the comparative example.
  • the lubricating performance additive of the present invention is very effective in terms of lubricating performance.
